Hello Lucy!
I can understand your concern.
May i have a more detailed history?Is there family history of asthma or allergy?
i would like you to get your child's serum immunoglobulin levels checked because he had one life threatening infection in 1st year of life and repeated episodes of infective illness.Though this time its viral and it will settle on its own but still i would recommend to go for that.
Give him saline nebulizations 6 hourly with 10 drops of
salbutamol solution. Take care of the
heart rate,if it increases more than 150/min,stop nebulizations.
Give him syp.
Doxophylline 2.5 ml Twice daily for 1 week and monteleukast sachet 4mg at night for 3 months.
Give him some good
anti histamines like levocetrizine for a week.
You can also give a natural icy leaves extract containing syp. twice daily for a week or try
home remedies like a teaspoon of honey in a glass of luke warm water given once daily.
Hope it will help.
Wishing your child good health :-)
